Personalised weight-management programme The 1:1 Diet has announced the winners of its annual Slimmer Awards following a glamorous ceremony in Birmingham.

The winners, chosen from 15 shortlisted candidates, achieved a staggering 40 stone 5 pounds of weight loss between them. Their stories reflect not only remarkable physical transformations but also extraordinary resilience, from paramedics determined to maintain peak health on the frontline, to individuals overcoming major life events such as baby loss or a diagnosis of type 2 diabetes. Each winner represents strength, courage, determination and health.

The shortlisted candidates were reviewed by a panel of experts, including world-renowned nutritionist for The 1:1 Diet, Mark Gilbert, and head of the Direct Selling Association, Chris Vernon. Joined by Alex Jones and Hannah Bullock from Cartwright Agency, the panel carefully selected five winners whose journeys were truly life affirming.

This year’s winners included:

  • Woman of the Year: Phillipa Smith, who overcame baby loss at seven months pregnant and lost 16 stone
  • Man of the Year: Frontline paramedic Aidan Pritchard, who dropped 6 stone 2 pounds and is now planning his wedding
  • Maintainer of the Year: Ann Barrowman, who lost 7 stone 10 pounds after suffering a devastating heart attack and has maintained her weight for two years
  • Transformation of the Year: Daisie Jenson, who was at risk of a heart attack at just 25, and shaved off 7 stone 6 pounds
  • The Wellbeing Award: Barry McCann, who shed 3 stone 1 pound and reversed his type 2 diabetes, sleep apnea and turned his mental health around

Each winner has worked closely with a dedicated Consultant, who developed a personalised plan and provided ongoing support throughout their slimmers’ weight-loss journey. This level of guidance is a cornerstone of The 1:1 Diet and ensures participants not only achieve but sustain their results.

The awards form a key part of the Corby-based company’s annual marketing and engagement strategy, highlighting the vital role of Consultants in driving client success and delivering measurable health outcomes.

Nutritionist Mark Gilbert said: “These annual awards allow us to celebrate and recognise not just the inspiring people who have transformed their lives, but also the Consultants who are by their side week in, week out helping them reach their goals. The event brings our slimmers together to share their journeys, celebrate achievements and inspire each other.

“As exemplified by our Maintainer of the Year, Ann Barrowman, who’s kept almost 8 stone off for over two years, The 1:1 Diet isn’t just effective for losing weight but for long-term maintenance of weight loss too. That doesn’t just apply to Ann, a four-year study of The 1:1 Diet, published in The American Journal of Clinical Nutrition, showed 100% of weight loss achieved at one year can be maintained long term.”

Josie Heath-Smith, Consultant at The 1:1 Diet, added: “I’m so proud of every one of my slimmers, including Woman of the Year, Phillipa Smith. Having lost 5 stone 7 pounds on the diet myself, I became a Consultant to share my passion and knowledge for the programme. Seeing the dedication of my clients every day is inspiring. The Slimmer Awards are a wonderful opportunity for people on the same journey to come together, celebrate their achievements and motivate each other to keep going.”

Previously known as The Cambridge Weight Plan, The 1:1 Diet was launched in 1984 and has since helped thousands of people lose weight, improve their health, and, in some cases, reduce or reverse type 2 diabetes. With support from dedicated Consultants, participants follow a tailored plan using meal replacements and products designed to provide a nutritionally complete method of weight loss and weight maintenance.
